Thanks for the reply tsuma54. The reason for the delay in responding was that I was even having trouble locating this thread again.
I was finally able to open the file I was talking about, which is over on Arkham Central, but that was an expansion for Eldritch Horror. I'm pretty sure that the one created by Ornendil is for Arkham Horror, but I have been unable to locate it. He has a long discussion about it here: https://community.fantasyflightgames.com/topic/290671-masks-of-nyarlathotep-by-orendil/
It looks like the images have been deleted or at least I click on the icons and nothing happens. I've put together a few of the fan-created expansions and this one is mentioned on one of the cards, I think in Door to Saturn (Africa), if I'm not mistaken, and I became curious about possibly adding it to my collection.
I thought perhaps Ornendil was still around and could provide me with a link or maybe Julia would see this and respond. She was very active with Arkham Horror at one time and was very much engaged in the above discussion.
Now that I know where to find this thread, my responses won't be so delayed; although, I do use the library and have a limited amount of time allotted to me here.
